The ISO/IEC 20000-1:2018 standard focuses on improving IT service management processes for organizations, enhancing service quality, and promoting compliance through structured management systems. Key changes in the 2018 revision include an alignment with common ISO structural guidelines, the introduction of new requirements in areas like asset and knowledge management, and a reduction in mandatory documented procedures. The transition period for organizations already certified under the previous version extends up to three years, emphasizing the need for training and gap assessments for compliance.
